What Car? Q&A - Introduction

Want to know if you've been given a fair price for your part-exchange, or if you can teach someone else to drive even though you've only just passed your test?

Can't work out whether you should buy a Honda Accord or a Nissan X-Trail, or maybe you don't understand why a Mercedes C200 doesn't have a 2.0-litre engine.
